【摘要】：目前,预防性养护的研究主要集中于高速公路干线沥青路面,针对服务区、收费广场水泥混凝土铺面预防性养护的研究较少。由于服务区、收费广场的水泥混凝土铺面状况会对高速公路服务水平造成较大影响,同时水泥铺面一旦出现损坏,维修极其困难,本文针对收费广场、服务区水泥混凝土铺面的使用特性,结合养护工作实际,提出高速公路收费广场、服务区水泥混凝土铺面预防性养护的概念,从“检测、分析、决策、实施”四个环节研究建立水泥混凝土铺面预防性养护的工作内容、评价指标和维修方法,以确保水泥混凝土铺面的良好使用状况。本文以单位所辖高速公路收费广场、服务区水泥铺面使用状况的调查为基础,首先分析了水泥混凝土铺面预防性养护的内容,进而提出水泥铺面的预防性养护标准,同时考虑到水泥混凝土铺面养护的“快通”要求,提出了局部快速修复的预防性养护措施。主要工作如下：首先,本文分析了水泥路面和沥青路面的主要病害及其成因,在此基础上,将水泥路面和沥青路面预防性养护的特点进行了对比,进而分析了水泥混凝土铺面预防性养护的内容；其次,对单位所辖的广靖锡澄高速、盐靖高速和启扬高速沿线服务区的水泥混凝土铺面状况进行调查,以铺面破损状况和板底脱空情况作为主要调查内容,以此为基础,总结了服务区水泥混凝土铺面的主要病害,通过对比分析,选择脱空率和错台损坏率作为预防性养护的指标,并给出了指标界限值,确定以脱空率小于25%,错台损坏率小于1%作为水泥混凝土铺面的预防性养护标准。最后,考虑到水泥混凝土铺面的养护维修往往需要较长的养生时间,不满足快速开通交通的要求,本文提出了基于聚氨酯注浆技术的水泥铺面预防性养护措施,该措施能对板底脱空和错台病害进行局部快速修复。通过在盐靖高速刘陈服务区进行现场试验,证明了该措施在工程实践中的可行性。
[Abstract]:At present, the research of preventive maintenance is mainly focused on the asphalt pavement of highway trunk line, but the research on preventive maintenance of cement concrete pavement in toll plaza is less.Because of the service area, the cement concrete pavement of the toll plaza will have a great impact on the service level of the highway, and once the cement pavement is damaged, it is extremely difficult to maintain. This paper aims at the toll plaza,The use characteristics of cement concrete pavement in service area, combined with the practice of maintenance, the concept of preventive maintenance of expressway toll plaza and service area cement concrete pavement is put forward.In order to ensure the good use of cement concrete pavement, four links are studied to establish the working content, evaluation index and maintenance method of preventive maintenance of cement concrete pavement.Based on the investigation of the use of cement pavement in expressway toll plaza and service area, this paper first analyzes the content of preventive maintenance of cement concrete pavement, and then puts forward the preventive maintenance standard of cement pavement.At the same time, the preventive maintenance measures for local quick repair are put forward considering the requirement of "quick pass" for cement concrete pavement maintenance.The main work is as follows: firstly, this paper analyzes the main diseases and their causes of cement pavement and asphalt pavement, and compares the characteristics of preventive maintenance between cement pavement and asphalt pavement.Then the content of preventive maintenance of cement concrete pavement is analyzed. Secondly, the condition of cement concrete pavement along the service areas of Guangjing Xicheng High Speed, Yan-Jing High-Speed and Qiyang Expressway is investigated.Taking the condition of pavement breakage and the condition of slab bottom void as the main content of investigation, this paper summarizes the main diseases of cement concrete pavement in service area. Through comparative analysis, the void ratio and failure rate of staggered platform are selected as preventive maintenance indexes.The limit value of the index is given and it is determined that the void ratio is less than 25 and the damage rate of the stagger is less than 1% as the preventive maintenance standard for cement concrete pavement.Finally, considering that the maintenance and repair of cement concrete pavement often requires a long time of health maintenance, which does not meet the requirements of rapid opening of traffic, the preventive maintenance measures of cement pavement based on polyurethane grouting technology are put forward in this paper.This method can be used to repair the defect of the floor and the fault of the plate.The feasibility of this measure in engineering practice has been proved by field test in Liuchen service area of Yanjing Expressway.
